Not wrapping but folding: Bacteria also organize their DNA, but they do it a bit differently
Some bacteria, it turns out, have proteins much like ours that organize the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for.....»»
New study shows outdoor recreation noise affects wildlife behavior and habitat use
